Is Uber unconstitutional or out of control fees and regulations?

I just read a story about suit by taxi companies suing Uber:

The suit from taxi medallion owners and financiers argues that letting Uber make pickups from an app, while at the same time it can avoid the burdensome fees and regulations that are dumped onto cabs, is unconstitutional.

Is it possible that they are suing wrong people? Maybe they should sue local governments who are out of control when it comes to new rules, regulations and taxes? Every time one of them sneezes there is a new regulation. My guess, adding taxis to Uber app didn't help.

Taxi companies claim ‘ehail’ rules for Uber are unconstitutional
